Guidance for Implementation of Traffic Incident Management Performance Measurement TRB’s National Cooperative Highway Research Program (NCHRP) Project Kelley Klaver Pecheux, PhD Applied Engineering Management Corporation (AEM) T3 Webinar on TIM Performance Measures June 12, 2014

OVERVIEW OF PRESENTATION Project objectives Research approach Expected research products High-level overview of guidance Project timeline Guidance for Implementation of TIM Performance Measurement

PROJECT OBJECTIVES Guidance for Implementation of TIM Performance Measurement Develop concise guidance on the implementation of TIM performance measurement that is applicable to a broad spectrum of transportation and incident responding agencies. Develop a model database (including schema) for the data elements and performance measures suitable for eventual aggregation of performance measures at a state and national level.

RESEARCH APPROACH Conduct a review of existing literature on TIM and TIM performance measurement. Conduct limited telephone interviews with TIM agencies/practitioners. Guidance for Implementation of TIM Performance Measurement

EXPECTED RESEARCH PRODUCTS Written guidance document. – Download or purchase from TRB. Online version of the guidance. – Accessible via the TIM Network website. – Allow for questions and comments to create a dialogue regarding TIM performance measurement. Guidance for Implementation of TIM Performance Measurement

HIGH-LEVEL OVERVIEW OF GUIDANCE General guidance on TIM performance measurement. Model TIM performance measurement database. Incident Timeline Guidance for Implementation of TIM Performance Measurement

GENERAL GUIDANCE ON TIM PERFORMANCE MEASUREMENT TIM performance measures, definitions, and current practices. How to calculate the performance measures. Putting performance measures into context using data on incident characteristics (e.g., incident severity, lanes blocked). Data sources (e.g., TMC, law enforcement, SSP). Challenges with TIM data (e.g., inconsistent definitions; availability; quality; data sharing, exchange, and integration). Data mining, reporting, and visualization techniques. Summary of interviews. Key points for success.

MODEL TIM PERFORMANCE MEASUREMENT DATABASE Database terminology. Data elements. Database schema. Data dictionary. Database scripts for creating the database and populating the look-up tables (downloadable from website). Analysis of performance using the various data elements in the database. Example applications of the model database, including the selection of performance measures and targets, database queries and scripts, data mining, presentation of performance measures, and interpretation of results. Guidance for Implementation of TIM Performance Measurement

PROJECT TIMELINE Project started in April Revised draft written guidance has been submitted. Beginning to develop online version of guidance (over summer). Will demo the online guidance to the project panel in Aug/Sept Project will be completed by the end of October Guidance for Implementation of TIM Performance Measurement
